The object of this invention is to provide a simple and cheaplyconstructed holder device or hand appliance for use in compactlyassembling and firmly holding the parts of a safety razor, with blade inposition, preparatory to placing the assembly (i. e., holder device andrazor parts) into a receptacle containing sterilizing or disinfectingliquid, the compact mode of assembling the razor parts permits a smallreceptacle to be used and yet enables the razor parts to be easilyremoved and connected for use from time to time, and this withoutnecessity for removal of the blade from between its cover and guardplates.

Broadly, a device for the purpose indicated and according to myinvention consists of a base which carries retaining means for firmlyholding the cover and guard plates of a safety razor with interposedblade such that the same may be readily removed as a unit, and means onsaid base for separately securing the detached handle of the safetyrazor in parallel disposition relative to and in close proximity withthe cover and guard plates when positioned.

According to one simple mode of construction said device comprises abase, two uprights spaced apart and extending upwardly from said base,one of said uprights being formed with a longitudinal slot open at itsupper end for the purpose of permitting the handle and blade-locatingprojections on the cover plate to be accommodated when the cover andguard plates of the safety razor with interposed blade are positioned asa unit between said uprights, and a screw-threaded pin secured to andextending upwardly from said base whereon the handle of the safety razormay be separately secured in an upright position.

The space between said uprights may be such that when the handle of thesafety razor is disconnected, subsequent to the cover and guard plateswith interposed blade being positioned between the uprights, theflattening out of the blade from its flexed position moves and holds thecover and guard plates in retaining abutment with adjacent uprights.

The holder device with razor parts in position may be placed inside areceptacle containing sterilizing or disinfecting liquid and fitted witha removable cap adapted to seal an open end of said receptacle.

I will further describe my invention with the aid of the accompanyingsheet of explanatory drawings which illustrate, by way of example only,one mode of carrying my invention into eifect.

In said drawing:

Fig. 1 is a front view,

Fig. 2 a side elevation, and

Fig. 3 a plan view, of a device constructed in accordance with myinvention for use in compactly assembling and firmly holding the partsof a safety razor, with interposed blade, preparato-ry toplacing theassembly into a receptacle containing sterilizing or disinfectingliquid.

Fig. 4 is a side elevation showing the safety razor with interposedbladeas when the safety razor is in use-placed loosely between spacedupright plates of the holder device.

Fig. 5 is a plan view of Fig. 4.

Fig. 6 is a further plan view showing the handle of the safety razorpartly unscrewed to cause the razor blade to flatten out from its flexedposition so as to move the cover and guard plates into abutment withadjacent upright plates of the device whereby the cover andguard platesand blade become firmly held thereon.

Fig. '7 is a side elevation showing the handle of the safety razorcompletely detached from the cover and guard plates of the safety razorand fitted separately onto the device, the whole assembly being showninserted into a receptacle containing disinfectant fluid.

Fig. 8 is a plan view of Fig. '7, the receptacle being shown in section.

In the several views like characters of reference denote like orequivalent parts wherever they occur.

Referring to the drawing, the device includes a base plate, designateda, which may be provided on its underside with small studs or foot restsb, b and on its upper side there is securely mounted two upright plates0, c suitably spaced apart one of which, i. e., plate c is preferablysomewhat longer than the other and contains a longitudinal slot c whichis open at its upper end. Also secured on said base plate a is a shortscrew-threaded pin d of such size as to be engageable with the usualscrew-threaded socket of a handle 2 of an ordinary safety razor whendetached and fitted thereto. A reduced lower end of pin d which securesthe latter and passes through base plate a may constitute the foot rest12.

In applying a safety razor with blade and handle in situ to my device,according to the preferred mode of usage, the handle a of the safetyrazor is held by the hand and the razor assembly, i. e., cover plate 7,flexible blade g and guard plate h, is passed downwardly between saidupright members 0, c --as in Fig. 4the bladelocating projections f andhandle 2 of cover plate 1 being accommodated in the slot c --which isshaped for this purpose-of said slotted plate The space between theuprights c, c is such that when the handle e is partly unscrewedas inFig. 6-after the safety razor has been initially positioned-as in Figs.4 and 5--the spring action of the blade g in returning from flexed toflat position causes the cover and guard plates h, respectively, to moveapart and firmly holds the same in retaining abutment with the adjacentuprights 0, 0 Then the handle e is completely detached from thescrew-threaded pin f of cover plate 7 and screwed onto the correspondingscrew-threaded pin 01 on the base plate a so as to be parallel and inclose proximity with the positioned cover and guard plates. The wholerazor assembly, with blade in position, may now be lifted and insertedby means of the handle e in a tin or other receptacle containingsuitable sterilizing or disinfecting liquid until again required foruse.

When wanted, the assembly is lifted from its container, again by meansof the safety razor handle e, which is then disconnected from itsanchorage d, on base plate a and reconnected with the screw-threaded pinf of cover plate 1: if the handle e is now screwed on tight the coverplate J and guard plate h will move inwardly free from the adjacentuprights c, 0 Whereupon the safety razor complete is now free to be slidupwardly by the aid of its reconnected handle e to release it frombetween said uprights c, 0 The handle e if necessary may be subsequentlytightened to finally clamp the blade g rigidly between the cover plate Iand guard plate h.

In a convenient mode of construction and as illustrated on the drawing,said spaced uprights c, c are formed out of a single piece of suitablybent sheet metal conveniently secured to base plate a by heads :i offoot rests b and it may be arranged that said upright plates 0, 0 shallhave an inward spring tendency so as to ensure that the razor partsshall, when positioned, be held firmly until required for re-use. Inanother simple construction, said uprights c, c may be constituted byframes of appropriately bent wire extending upwardly from base a.

The device with compactly assembled razor parts may be snugly disposedin a small cylindrical receptacle 7cas shown in Figs. 7 and 8provldedwith, say, a tightly fitting screwed lid or cover Z having wings 1 so asto be always ready for use in sterilized condition, and this withoutdanger of the sterilizing liquid evaporating or being spilt.

My holder device may be constructed throughout of metal or any othersuitable material.

What I claim as my invention and desire to secure by Letters Patent is:

A device for use in compactly assembling and holding the parts of asafety razor with interposed blade preparatory to placing the assemblyinto a receptacle containing a sterilizing liquid comprising a base,uprights extending from said base and spaced apart a distance greaterthan the thickness of the assembled razor head when the blade is flexed,but less than the thickness of the assembled razor head when the bladeis flat, one of said uprights being formed with a lcngitudinal slot openat its upper end for the purpose of permitting the handle andblade-loeating projections on the cover plate to be accommodated whensaid cover and guard plates of the safety razor with interposed bladeare positioned as a unit between said uprights and a screw-threaded pinsecured to and extending upwardly from said base whereon the handle ofthe safety razor may be separately secured in an upright position.
